• Surface-mount design facilitates automated SMT assembly and standard reflow soldering processes.
• RoHS compliant with lead content in the glass seal falling under regulatory exemptions.

Crystals Applications

• Portable USB interface cards
• Personal Digital Assistants (PDAs)
• Digital cameras

Crystals Procurement Notes

Verify current availability status as this component may be subject to discontinuation or limited supply conditions. Confirm that the specific 20pF load capacitance matches the target circuit design requirements before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 12.288 MHz clock source is required in a compact 2-SMD form factor. Ensure the application environment remains within the specified -40°C to +85°C operational range and that the 20pF load capacitance aligns with the oscillator circuit parameters.

Crystals Part Context

This part belongs to the TXC 7A series, which specializes in 5x3.2mm glass-sealed crystals. This series is engineered to offer superior reliability against thermal cycling and humidity compared to resin-packaged alternatives, making it suitable for demanding consumer electronics.

Crystals Replacement Considerations

The 7A-12.288MAHK-T is a documented substitute offering identical 12.288 MHz frequency but with a 20pF load capacitance and 30ppm tolerance, ensuring functional compatibility within the same package constraints.
